Nagaoka Tenmangu Shrine is a shrine located in Tenjin, Nagaokakyo City. It is affectionately known as "Tenjin-san" by the local citizens. Nagaokakyo City was once called Nagaoka, Otokuni County, Yamashiro Province. In the 3rd year of Enryaku (784), Emperor Kanmu moved the capital from Heijo-kyo to Nagaoka-kyo, and Nagaoka Tenmangu Shrine is located on the southwestern edge of the former capital. The following two items are provided: 1. Goshuin (temple stamp) 2. Yuisyo-sho (historical document) It is said that during the Heian period, Sugawara no Michizane, along with Ariwara no Narihira, one of the Six Poetic Immortals, enjoyed poetry and music here. When Sugawara no Michizane was demoted to Dazaifu in Kyushu, he sent a wooden statue as a memento, and it is said that this was enshrined as the sacred object, marking the beginning of Nagaoka Tenmangu Shrine. The main shrine was relocated from Heian Jingu Shrine. The blooming Kirishima azaleas in late April at Hachijo-ga-ike Pond are magnificent, and the view from the water bridge is also beautiful.
